Da acusação às professoras pelo aprisionamento do sujeito em um diagnóstico a uma interrogação acerca da posição do analista

This study arises with two questionings: what is the usefulness of a diagnosis in school? And what moves that demand for diagnosis? Such questions were drawn up in answer to a diagnostic demand produced in the context of our internship in Scholar/Educational Psychology. On the perspective of working these issues, we conducted a literature research on diagnosis, with regard to its history, as a review of the psychoanalytic literature about the subject. This venture led us to a new interrogation: what are the elaborations that teachers produce from the child diagnosis, which place her as having special educational needs? The need of deciding the method that would lead us to answer such question, taking as reference the psychoanalytic theory, led us to an incursion to the subject research in psychoanalysis. This tracking points us that, according to Freud, on what comes to psychoanalysis, theory and research go together and that psychoanalysis is not a totalitarian world vision. On Lacan, the research is from the analysand, research that always implies the analyst and its praxis. Such path forced us to position a change to question the positions we occupy, in this experience, guided by an analytical listening. To discuss our position, we started from two cases and submitted them to construction and analysis. As a result, we found out that there is no way to know in advance what will be done from a diagnosis, which will be its uses. Point we used to considerate devastating to a child. So, to us, all children that received a diagnosis would be destined to a tragedy and what the research has shown us is that not always, not all of them. Thus, more than knowing what moves the demand, the important is the subject uses and our position towards it so they can generate a work

As Faces e os Disfaces da Informalidade no Capitalismo Conteporâneo: Um Estudo do Comércio de Rua em Pau dos Ferros/RN

This paper discusses the expression of informality in contemporary capitalism. Thematic of relevance to the analysis of the reality of work today and the logic that moves the capital, its real presence in the lives of individuals. The street trading of Pau dos Ferros town, popularly known as "street market" was chosen as the search space. The main objective is to seize and examine the articulations and logic, present in the configuration of the street trading of this city, located in the state of Rio Grande do Norte, explaining the functionality of informality for capitalist accumulation, but also for the reproduction of segments of the working class. Our analysis is based in the perspective of totality, trying to grasp the historical determinations of the phenomenon in focus. It includes the analysis of the mechanisms used by the capital to reproduce itself in the current historical context, which has been implicated in the composition of the labor markets of different countries and in various forms of exploitation to which workers in general are subject. It also means discussing the development of capitalism in Brazil, the logic that permeates its dependence, and especially the use of over-exploitation of labor, as a lever for internal accumulation. The course of investigation consisted of theoretical research to form the basis of theoretical and methodological analysis and to outline the context in which our research object is inserted, and field research conducted in two phases: systematic observation, which allowed to map traders features and the infrastructure of commerce, and the conduction of interviews with key informants. The material collected was scrutinized according to analytical scheme inspired by the content analysis. Among the main considerations developed from the research process we include: the street trading of Pau dos Ferros remains shrouded in the majority sale of agricultural products, this demonstrates the structural characteristics of the region. However, the supply of this product is no longer restricted to the excess of small local producers. The presence of the dealer changed the distribution of the product, streamlining it. In parallel, business practices are developed, practices in which traded goods (industrial) reflect the moment of capitalist restoration, a larger business network. The reflections also made it possible to show that street trading follows developing on the basis of informal work, which gains functionality to the system, as it is configured as a space commonly used to drain part of the production, of industries (clothing/shoes), especially if the distribution is considered as an essential element of the complex process that aims at capital appreciation. This activity has been functioning as a place of employment and income generation for the subjects who are away from formal employment, masking, this way, unemployment, moreover, they allow them to continue as consumers. Such expressions reflect the ability and the logic of capital to expand and aggregate into so many realities. It is underway today, the logic that has led many workers to join the project of domination of capital, by the illusory chance to become capitalists. The aim has been to turn the subject into a consumer and the worker an enterprising

A imanência como lugar do ensino de filosofia

A intenção do presente artigo é pensar a problemática do ensino de filosofia a partir da obra de Deleuze e Guattari. Esses autores criaram uma série de conceitos, em seu fazer filosófico, para entender o que seria fazer filosofia, ou seja, para entender a atividade filosófica que se distanciasse de uma reflexão sobre alguma coisa e se fundasse em um ato de criação filosófica. Segundo os autores, existem quatro conceitos que corroboram para entender esse fazer filosófico, quais sejam: conceito, plano de imanência, personagem conceitual e problema. Tem-se como hipótese que tais conceitos podem contribuir para se pensar o ensino de filosofia na contemporaneidade de modo diferenciado do qual vem sendo tratado. Foi dada especial atenção a um desses conceitos: plano de imanência, engendrado na última obra conjunta desses autores, O que é a filosofia? (1997). Buscou-se, na obra desses autores, a caracterização de imanência e, consecutivamente, de plano de imanência para entender como se pode pensar o ensino de filosofia de forma diferenciada e de modo tal a distanciá-lo de uma adequação conceitual a um transcendente ou a um transcendental, a qual, no entender dos autores trabalhados, levaria o conceito de ensino a um dogmatismo conceitual. A proposta deste artigo é buscar uma saída para o problema, pensando o ensino de filosofia a partir da imanência mesma na qual este se produz.

A lição de Heráclito

Heráclito é conhecido na história do pensamento filosófico como o propositor da doutrina do mobilismo universal O tudo flui, nada permanece, asserção pela qual é comumente sintetizada, integra o cerne da Metafísica: suscita em Platão a não menos conhecida Teoria das Formas, que acabará por tomar-se o pensamento diretor da filosofia do Ocidente. Para melhor compreender essas ressonâncias, desenvolveremos algumas considerações sobre a essência do devir heraclítico.

Caracterização geométrica e parametrização de depósitos transacionais recentes e sua aplicação na modelagem de reservatórios petrolíferos

In this beginning of the XXI century, the Geology moves for new ways that demand a capacity to work with different information and new tools. It is within this context that the analog characterization has important in the prediction and understanding the lateral changes in the geometry and facies distribution. In the present work was developed a methodology for integration the geological and geophysical data in transitional recent deposits, the modeling of petroliferous reservoirs, the volume calculation and the uncertainties associate with this volume. For this purpose it was carried planialtimetric and geophysics (Ground Penetrating Radar) surveys in three areas of the Parnaíba River. With this information, it was possible to visualize the overlap of different estuary channels and make the delimitation of the channel geometry (width and thickness). For three-dimensional visualization and modeling were used two of the main reservoirs modeling software. These studies were performed with the collected parameters and the data of two reservoirs. The first was created with the Potiguar Basin wells data existents in the literature and corresponding to Açu IV unit. In the second case was used a real database of the Northern Sea. In the procedures of reservoirs modeling different workflows were created and generated five study cases with their volume calculation. Afterwards an analysis was realized to quantify the uncertainties in the geological modeling and their influence in the volume. This analysis was oriented to test the generating see and the analogous data use in the model construction

Caracterização morfológica e sedimentar do talude continental (foz do Amazonas)

Created on 3 december 1997, the REMPLAC (Program for Assessment of Mineral Potencial of the Continental Shelf), this porgram aimed to make the basic survey, systematic geological and geophysical continental shelf, detail, at an appropriate scale, sites geo-economic, and perform the analysis and evaluation of mineral deposits. The REMPLAC should continue the efforts of Global Recognition Program of the Brazilian Continental Margin REMAC closed in 1978, the operations Geophysical Sea (GEOMAR) developed by the Directorate of Hydrography and Navigation and the various initiatives of the Program of Marine Geology and Geophysics (PGGM). Despite the high interest on the Amazon platform, there is little information o their morphology and sediment characterization, and in order to fill this gap, the present work samples sedimentological point followed by seismic acquisition. And the studies were to characterize the possible area of interest as being directly influence by tides, which sediments are reworked throughout the platform featuring grain angle with sharp corners, and the carbonate content increases as it approaches the breakdown the platform, and the bodies found outside the foraminifera and mollusks. However, diverging with organic matter that reduces its concentration as it moves away from the coast. The seismic profiles do not get satisfactory results because of low visibility, however, to correlate with the spot samples, of sediment were possible morphological characterization of the area.

Expansão urbana de Mossoró :(período de 1980 a 2004)

The purpose of this Academic Work is to identify the process of urban expansion of Mossoro city, connect them with the economy that moves the society of Mossoro. This analysis is about the period from 1980 to 2004 and the economy activities selected are compose the structure of the Mossoro' s life, fixing shapes, functions and contents of the city territory, especially in its urban space to understand the present process of urban expansion and its relations with the dynamic of the city we recall history of this territory, wich as a urban word, connect the changes with the primary economy actives - commerce and sea salt extraction. ln this relation between the present process of urban expansion and the dynamic of the city economy, the economy activities studies where the sea salt extraction, and irrigated fruit crops organizes the space so they can be viable in all stages - production, trade and circulation - to be viable they change, amplify and build a urban space together with public policy, that also increases with the arrival of new inhabitant, service structure, mount by the public administration as well as by private resources. This work point out the needs of a development a new main plan for Mossoro, that will reorganize it's territory, but also grant the needs of its society, wich desires a more given city, where citizenship will be exercise with dignity

Presença de material eletrodenso sob a membrana vitelina do ovo de Scaptotrigona postica latr. (Hymenoptera, Meliponinae) durante a fase inicial da embriogenese

The present paper reports the presence of an electrondense material of unknown nature distributed under the viteline membrane of Scaptotrigona postica egg. The dorsal side layer is thicker then the ventral one. In eggs newly oviposited the material is gradually distributed inside the plasmalema invaginations. Later on (12 hs after oviposition) when a blastoderm is already formed around the egg, the material moves to the intercellular space. on the sequence of the development there was no more indication of the material under the membrane.

Three-boson recombination at ultralow temperatures

The effects of trimer continuum resonances are considered in the three-body recombination rate of a Bose system at finite energies for large and negative two-body scattering lengths (a). The thermal average of the rate allows to apply our formula to Bose gases at ultra-low temperatures. We found a good quantitative description of the experimental three-body recombination length of cesium atoms to deeply bound molecules up to 500 nK. Consistent with the experimental data, the increase of the temperature moves the resonance peak of the three-body recombination rate to lower values of vertical bar a vertical bar exhibiting a saturation behavior.

Effect of a frictional force on the Fermi-Ulam model

The dynamical properties of a classical particle bouncing between two rigid walls, in the presence of a drag force, are studied for the case where one wall is fixed and the other one moves periodically in time. The system is described in terms of a two-dimensional nonlinear map obtained by solution of the relevant differential equations. It is shown that the structure of the KAM curves and the chaotic sea is destroyed as the drag force is introduced. At high energy, the velocity of the particle decreases linearly with increasing iteration number, but with a small superimposed sinusoidal modulation. If the motion passes near enough to a fixed point, the particle approaches it exponentially as the iteration number evolves, with a speed of approach that depends on the strength of the drag force. For a simplified version of the model it is shown that, at low energies corresponding to the region of the chaotic sea in the non-dissipative model, the particle wanders in a chaotic transient that depends on the strength of the drag coefficient. However, the KAM islands survive in the presence of dissipation. It is confirmed that the fixed points and periodic orbits go over smoothly into the orbits of the well-known (non-dissipative) Fermi-Ulam model as the drag force goes to zero.
